Claims. (Cl. 241202) My invention relates to gyratory Crushers having a plurality of discharge openings and particularly to means to convey crushed material from the discharge openings to a remote place of use or storage.

It has been customary to convey crushed material from a gyratory crusher having a plurality of discharge openings by a conveyer traveling relative to each discharge opening.

lt is the principal object of my invention to use for this purpose conveying means including a single conveyer or aligned conveyers forming a continuous line of feed.

lt is another object of my invention to utilize the foundation of the crusher in carrying out the principal object of the invention.

Another object of the invention is to provide feeding means relative to an empty portion of a conveyer to regulate the feed of the crushed material onto said portion of the conveyer and prevent undue wear of the conveyer.

It is a further object of the invention to provide the foundation of the crusher with a tunnel for the travel of a conveyer therethrough and feed boxes above the tunnel to receive crushed material from the discharge openings of the crusher and deliver the crushed material onto spaced portions of the conveyer.

A further object of the invention is to form the foundation of reinforced concrete to provide a substantial support for the crusher and tunnel.

Other objects and advantages of the invention will be set forth in the detailed description of the invention.

In the drawings accompanying and forming a part of this application,

Figure l is an elevational view of a gyratory crusher having two discharge openings and a foundation in section to show the embodiment of the invention for convey ing crushed material to a place remote from the crusher by a single conveyer.

Figure 2 is a fragmentary view looking from the line 2-2 of Figure l in the direction of the arrows to show the relationship between a feed box and the foundation.

Figure 3 is a view similar to Figure l showing a modi tied form of conveying means wherein the conveyor is divided into two sections, one section traveling at a slower rate of speed to receive the crushed material from the discharge openings of the crusher and the other section conveying the crushed material to a place remote from the crusher.

Figure 4 is a View similar to Figure 2 looking from the line 4--4 of Figure 3 in the direction of the arrows.

The embodiment of the invention is shown in combination with a gyratory crusher indicated in a general way at 5 and having a plurality of discharge openings, in the present illustration two openings 6, in diametrically opposite portions thereof provided with chutes 7.

The crusher S is supported in upright position by a concrete foundation 3 reinforced, as indicated at 9 in Figures l and 3, and arranged with a center recess to accommodate and support a motor and eccentric mounting of States Patent O in Figures l and 3.

the crusher, as indicated at 11 in Figures l and 3. The chutes '7 are mounted in passages 12 in the foundation.

The foundation is also arranged with a tunnel 13 extending therethrough below the recess 10 and transversely of the vertical axis of the crusher. The reinforcement 9 of the foundation will prevent collapsing of the tunnel and assure a rm support for the crusher. The purpose of the tunnel is to permit the conveying of crushed material from the crusher to a remote place by a single conveying means.

This conveying means is shown in Figures l and 2. as comprising an endless belt conveyer 14 suspended between two drums, only one drum being shown at 15 in Figure l, and the upper stretch of the conveyer being supported by rollers 16 and the lower stretch supported by rollers 17. The drum 15 is rotatably mounted adjacent to and exteriorly of the end of the tunnel 13 constituting the entrance to the tunnel, as indicated at 18, and the other drum, not shown, of the conveyer is located at the place. of delivery of the crushed material, which place may be a considerable distance from the crusher. The form of conveying means shown in Figures l and 2 is used with crushers producing tine crushed material of light weight.

In Figures 3 and 4, the crusher 5 is adapted to produce coarser and heavier crushed material than the crusher shown in Figures l and 2. To convey such coarser and heavier material without damaging the conveying means, an endless conveyer or feeder 19 is suspended between sprocket wheels 2i) mounted exteriorly of the opposite ends of the tunnel 13 and actuated at a lower rate of speed than the conveyer drum 15. The conveyer 19 is constructed of heavy steel plates 21 pivoted to each other and the ends of the pivots extended from the opposite sides of the plates to support rollers 22 engaging rails 23, as shown in a general manner in Figures 3 and 4. The conveyer 19 delivers the crushed material to a conveyer 24 of a structure similar to the conveyer 14 which conveys the crushed material to a remote place of use or storage. The conveyer 24 is actuated at a faster rate of speed than the conveyer 19. The crushed material is guided from the conveyer 19 to conveyer 24 by spaced side walls 25 and a sloping wall 26 supported by the side walls 25 and interposed between the conveyers 19 and 24, as shown in Figure 3. The conveyers 19 and 24 form a continuous conveying means divided into two sections with the section 19 traveling through the tunnel 13 at a reduced rate of speed and of greater strength than the other section 24 traveling from the tunnel to the remote place of use or storage of the crushed material.

In the use of either form of conveying means shown in Figures l and 2, or Figures 3 and 4, the crushed material discharged from the openings 6 is directed by the chutes 7 into feed boxes 2.' and 28 mounted by means 29 on opposite sides of the foundation 8 in alignment with the chutes 7' with the lengths of the boxes extending from adjacent the top of the foundation to the top wall of the tunnel 13. The top of the boxes may or may not be closed, but said boxes 27 and 23 are arranged with bottom walls. The bottom wall 313 of the box 27 slopes inwardly toward the foundation and is spaced from an obliquely extending wall portion 31 of the foundation to form an obliquely extending delivery opening to the conveyer 14 or 19 at the entrance end itt ot' the tunnel 13. The size of this delivery opening is regulated by a gate 32 adjustably mounted on the bottom wall 39, as indicated at 33 The bottom 30 and gate 32 form a feeder which will reguiate the quantity and rate of delivery of the crushed material onto the upper stretch of the conveyer 14 or 19 traveling into the tunnel entrance portion 1S so that the conveyer' will not be unduly worn as the portion of the upper stretch of the conveyer receiving said delivery of crushed material is empty or bare. The crushed material in the feed box 28 is delivered by a chute ICC 34 to the portion of the upper stretch of the conveyer 14 or 19 which has passed through the exit end 35 of the tunnel 13. It is not necessary to provide a feeder at the delivery portion of the box 28 as the upper stretch of the conveyer is protected by the crushed material delivered to the conveyer 14 or 19 by the feeder 30, 32 from the box 27.

Having thus described my invention, I claim:

1. In means for conveying crushed material from a gyratory Crusher having a plurality of discharge openings and supported in upright position on a foundation arranged with a tunnel extending through the foundation in a direction transversely of the vertical axis of the crusher, the improvement comprising a feed box mounted on the side of the foundation in alignment with each discharge opening of the crusher to receive crushed material from the discharge opening and provided with a delivering portion, one delivering portion being at one end of the tunnel and the other delivering portion being at the opposite end of the tunnel, and a conveyer traveling through the foundation tunnel in vertical alignment below the feed boxes to receive crushed material from the delivering portions of the feed boxes and convey said material to a place remote from the feed boxes and the Crusher, wherein the delivering portion of one feed box delivers crushed material onto an empty portion of the conveyer entering the tunnel and the delivering portion of the other feed boxes deliver crushed material onto the portion of the conveyer covered with crushed material.
